That seems overly complex. I would instead wait until the required data is
available before running set_fact:
- vars:
che_keycloak_lookup: "{{ lookup('k8s',
api_version='route.openshift.io/v1',kind='Route',resource='keycloak',namespace='che')
}}"
block:
- debug:
msg: Waiting for data propagation...
until: "'spec' in che_keycloak_lookup"
retries: 30
delay: 10
- name: Get Che Keycloak facts
set_fact:
che_keycloak: "{{ che_keycloak_lookup }}"
